Preparing the heater for use
Read the instructions carefully before the first use! The heater is painted with heatresistant paint and due to its chemical properties it may evaporate burning odours from its
surface when heated for the first times. Therefore we recommend the first heating up to
be done outdoors or in a well-ventilated sauna room. The first pre-heating must be done
without stones. If the sauna stove is heated up outdoors it should be done with a 2 metre
connecting pipe installed in order to get a good draught. In preheating the continuous
heating with 3-5 loads of wood should be enough to remove the anti-corrosion substances
from the heater.
One of the paint properties is that it reaches its final state only during the first heating
times. Thus rubbing and wiping of the painted surfaces should be avoided before the first
use. Handle the heater with care. The heater is likely to release paint odour for some time
as any other painted materials.
Adjustable feet
The heater can be equipped with optional adjustable feet (shown here). Adjustable feet
facilitate the installation of the heater on an inclined floor.
Installation point
Make sure there is enough space for installation and observe the safety distances. Heating
up requires 1 m x 1 m around the heater. Place the heater far enough from combustible
materials and protect the floor if the floor is tiled. See that there is space in the niche for air
circulation (minimum of 100 mm).
Remember that the sauna rocks decay over time causing fine-grained rock material to
fall to the floor with the steam water. The heat generated by the furnace and temperature
changes may also cause small metal flakes to fall to the floor which is a normal property of
metal.
Due to the above-mentioned facts it is a good idea to avoid using light-coloured materials
near the heater. Always check the heat resistance of the tiles with the supplier.
Keep the floor under the heater clean.Suojaetäisyyde
Minimum safety distances
Minimum safety distances between the heater and combustible materials:
from the sides and back of the heater: 500 mm
from the front of the heater: 1000 mm
from the top of the heater to the ceiling: min. 1200 mm
from the heater to the floor (see Floor protection): min. 50 mm
Statutory minimum safety distances to combustible materials can be reduced by half with
single-layer and by 75% with double-layer light protection.
